The SCART connector is a standard that enables the transmission of both digital and analog signals. Yes, and you can connect a high quality video source to your TV without intermediate coding.
To broadcast a movie on a TV from a laptop, it would be better to use a VGA-SCART adapter. It’s just that many TV models have a SCART connector, and many laptops have VGA.
In general, if we talk about wired ways to project an image from a laptop to a TV, then the most suitable option would, of course, be HDMI, because this standard allows you to transfer high quality video and sound without much time.
How to transfer with cable?
First, you need to note that there are two ways to display an image from one device to another:
In the first case, the following technologies are used:
This method of cable connection is considered to be the most optimal today for transferring media data from one device to another. This type of technology makes it possible to transfer files at high speed, and one cable allows you to transfer not only the image, but also high quality sound.
How do you transfer images from a laptop to a TV using this technology? It is enough to simply connect a pair of devices together with the appropriate cable. After that, on the TV, you should turn on AV mode and find the port to which the HDMI cable is connected. And on a laptop, you need to enter the on-screen settings, set the appropriate resolution and configure the correct display of the displays. That is, in fact, it will be possible to control two screens on a laptop. But in general, in such a situation it will be possible to use several modes:
- duplication. the same picture will be displayed on both displays;
- displaying on the screen of one device. then the display of another device will simply turn off and will be in sleep mode;
- screen expansion. in this mode, the TV will become like a second monitor.
you should only add that for the correct operation of this connection format, the corresponding driver must be installed on the laptop. It usually comes with video card drivers.
This connection standard was developed for the transmission of video images to digital devices. It was HDMI that replaced it. Its main disadvantage is that it does not support audio transmission. For this reason, you will need to use a TRS connector or adapter, it is also a mini-jack. And even more people are familiar with it as a headphone jack. To broadcast an image to a TV screen from a laptop, you will need to perform almost the same actions as in the case of HDMI. After that, you can start playing any file immediately.
The third format that allows you to implement the task considered in the article is called S-Video. This interface belongs to the analog type and allows you to transfer video files only in standard quality 576i and 480i, that is, video transmission in HD, and there is no more Ultra HD format. Few TV models have such a port, which is why, in order to make this type of connection, in most cases it will be necessary to get an S-Video. RCA adapter. In addition, there is still a limitation on the length of the cable. Models with a length of more than 2 meters should not be used, due to the fact that the longer the cable length, the lower the signal quality will be. This format also cannot transfer sound. Because of this, similarly with DVI, you will need to use a mini-jack.
Of the features in terms of setup, it should be noted that after the cable is connected, you will need to select an active signal source on the TV.
But the connection through this connector, although it is easy to do, but the transfer of the image through it is technically impossible. The specified standard was not conceived as a transfer of image and sound. Through it, you can only make the TV recognize the laptop as a flash drive, making it possible to view presentations, some text documents and images, but no more.
The only way to somehow use USB to dub a laptop display is to use the HDMI port on the TV as well. Then it will be possible to purchase an external video card, which, in fact, will be an adapter, and install the corresponding driver on the laptop.
But video playback in a certain quality will depend directly on the characteristics and capabilities of the external video card itself.
Another way to transfer images to a TV from a laptop or computer will be LAN. It is interesting in that it differs significantly from the above methods. LAN is a wired Ethernet type connection. If the TV is not equipped with a Wi-Fi module or there is no technical ability to connect it, then this option is the best solution.
To duplicate a PC image on a TV, you need to follow a certain sequence of steps.
- Connect the TV device to the router using a network type cable. For correct operation, the DHCP protocol must be correctly configured on the router. If this is not done, then you will need to register the network settings directly on the TV manually.
- Now you need to connect a laptop to the same network. And it doesn’t matter how to do it: using a wire or wirelessly.
- A program should be installed on the laptop to output files to the TV. Alternatively, you can use a software called “Home Media Server”. Even a person who does not understand the intricacies of laptop control can customize this program.
- It remains to open shared access to the necessary directories.
After that, you can transfer the necessary media files and play video and audio.
Another extremely popular image transfer interface is VGA. Almost any device today is equipped with such a connector. To create such a connection, the laptop and TV must have the appropriate connectors and cable. If all this is there, then you will need to do the following:
- insert the cable into the connectors on both devices;
- turn on the laptop and TV;
- now you need to select VGA as the main signal source;
- on a laptop, you should configure the connection and set a comfortable resolution.
To configure it, you need:
- on an empty place of the desktop, right-click;
- in the context menu, find the item “Screen resolution”;
- select the “Screen” menu;
- select the desired image broadcast mode;
- press the “Apply” button to save the changes.
By the way, it must be said that audio transmission is also impossible using the VGA connector. If you need to transmit sound, then you can use the already twice mentioned mini-jack connector.
How to display an image from a laptop to a TV?
Nowadays, almost everyone in the house has a TV, laptop and personal computer. The presence of such a large number of devices allows each family member to have their own device, which they can use at any time.
But this also opens up opportunities for displaying a picture from one device to another, for example, from a laptop or PC to a TV, because it is more pleasant to watch a movie on a 43-inch monitor than on a 19-inch one. In our article, we will learn how to do it correctly.
Wireless transmission options
As you can understand, if desired and technical capabilities, you can configure and wireless transmission of images from a laptop to a TV. One way to do this would be a DLNA connection. To use this technology, the TV must be a Smart TV and have a Wi-Fi module.
If you want to broadcast from a laptop to TV in this way, you will need to:
- connect both devices to the Wi-Fi router, on the TV you will need to specify the access point as the main one and enter the password;
- on a laptop, you will need to open the “Network and Sharing Center” section and make a server, and select your home network as the main network;
- now you need to select the files that you want to transfer, for which you need to click on the right mouse button, then enter the “Properties” and open the “Access” tab, now you need to switch the checkbox to the item “Share this folder”;
- now you can open the files you want on your TV.
By the way, if the TV and laptop support the Wi-Fi Direct function, then you can transfer files in such a way that it will be much faster.
Another way how you can project a video signal from a PC to a TV would be a technology called Miracast. In fact, thanks to it, the TV will become a wireless monitor of your PC. The advantage of this method is that the technology does not matter what video stream is broadcast. any video encoded with any codec and packed in any format will be transmitted. Even a file that is write protected will be transferred.
I must say that not all devices support this technology. For it to function fully, the equipment must run on an Intel processor. If it is, then to carry out the transfer, you will need to perform a sequential algorithm of actions.
- Activate Miracast (WiDi) on the TV. If this function is absent for some reason, then you just need to activate Wi-Fi. If you have a TV from the South Korean brand Samsung, then there is a special key called “Mirroring”.
- Now you need to launch a program called Charms on your computer.
- Here you need to click on the “Devices” button, then select “Projector”. Sometimes this key also has the signature “Send to Screen”.
- If the Miracast technology is supported by the personal computer, then the prompt “Add a wireless display” should appear.
- It remains only to confirm this in order to be able to broadcast the necessary content from a laptop to a TV.
If we talk about recommendations, then first of all, the user should clearly understand the characteristics and capabilities of the devices that are at his fingertips. Most often, problems arise due to the fact that users do not know which formats their equipment supports, and therefore often cannot decide on the correct type of connection.
The third aspect will be important for users who use a wireless connection. It consists in the fact that before starting work, you should make sure that the router is working and there is an Internet connection, if we are talking about LAN.
In general, as you can see, there are quite a number of ways to transfer images from a laptop to a TV.
Thanks to this, the user gets a lot of opportunities to find the most suitable option for him.
For information on how to display an image from a laptop on a TV, see the video below.
What you need to connect a laptop to a TV
You can transfer a picture from a laptop to TV by cable or via Wi-Fi. In the first case, they look at what ports are available on the equipment cases. Then they are connected with a cord and the picture is adjusted. The method is also relevant for transferring images from a stationary PC. The main thing is that the equipment is located close to each other, since the cables are usually not long enough.
Another way is wireless transmission, which is relevant when pairing modern technology. The inconvenience in the form of cable routing disappears immediately. Even if the TV is without Smart TV, there is an output. use of an additional external device.
You can display the image using a wired or wireless connection.
Ways to display an image
With a wired connection method, the ports on the devices may differ. for such situations, special adapters are used. But, if the data is digital, and the input to the TV is analog, you will have to buy a converter or set-top box.
The over-the-air option benefits from no wiring required. But it has a drawback. bandwidth limitations and the likelihood of signal interruption. The cable connection has one drawback. the limit on the length of the cord. However, if a laptop is connected, and not a stationary computer, things are much easier, because it is easy to transfer.
To display images from a computer to a TV, both devices are connected to a common network. New Samsung TVs support Wi-Fi Direct technology. this eliminates the need to connect to a router (the TV set creates its own network). All that remains for the user is to join it from the laptop.
To broadcast video from a laptop to a TV, a DLNA server setting is required. How it works. the user opens network access to those folders where the media content is stored. By connecting to your home network, you can display any content on the big screen.
To synchronize the laptop with the TV, they also use the explorer.
Configuring Network Discovery in File Explorer.
- Go to “Control Panel”. “Network” and click on “Network Discovery”.
- To complete the setting, just follow the prompts that appear on the screen.
Having configured the DLNA server, it remains to pick up the remote control and check if new signal sources have appeared in the list of available connections. By activating DLNA, they select the content that will be sent to the big screen.
Play files via DLNA server.
- Right-click on the desired file.
- Select the item “Play on” and specify the TV model.
There is another technology that allows you to duplicate the screen. WiDi Miracast. It works wirelessly. But here certain requirements are imposed on the laptop. a chipset from Intel, a discrete video card and a Wi-Fi adapter.
- Press “Menu” on the remote control.
- Select the “Network” section.
- Activate “Miracast / Intel’s WiDi”.
- Download the Intel Wireless Display program on a laptop, open.
- The available devices are displayed on the screen.
- Opposite the name of the TV press “Connect”.
Sometimes a PIN is requested. Usually this is a combination of numbers “0000” or “1111”. At the end of the WiDi technology setup, go to the “Charms”. “Devices”. “Projector” section, where they select the TV.
Selecting a device in WiDi Miracast.
Synchronizing two devices with an HDMI cable is the best way to transfer a picture from one screen to another. The advantage of this interface is a high data transfer rate, and not only video, but also multichannel audio.
To display a picture from one equipment to another, it is enough to combine them with an HDMI cable. Then on the TV press the “Source” button and switch the signal source (HDMI1, HDMI2). On a laptop, adjust the resolution and display display.
That is, from a laptop, you can control two screens at the same time and customize the appearance for the TV receiver:
- duplication. the image is shown on both displays;
- display on 1 screen. the second will be disabled at this time;
- screen extension. TV is used as a second monitor.
Before connecting the equipment with a cable, turn it off.
The Digital Visual Interface port is used to transmit clear image and video (FullHD, 3D). This method has a number of disadvantages. the interface is not capable of transmitting sound, plus you need to buy an adapter from DVI to VGA.
Digital Visual Interface Port.
There will be no delays during the broadcast, since the TV and laptop are connected directly with a cable. To solve the problem with sound, connect an audio system or external speakers through the audio input of the TV (located on the back of the case).
How to display an image from a computer on a TV. the best ways
Experienced tech owners often use a TV as an external display for a laptop. It is convenient, because watching your favorite movie on the big screen is much more pleasant. You can also stream games and work presentations. Getting an image from a laptop to a TV is not as difficult as it sounds. There are several connection options. “over the air”, using wireless technologies or by cable.
European standard for analog and digital signal transmission. Differs in specifications (for audio, video, controls). The advantage of SCART is the ability to connect a high-quality RGB video source to a TV (bypassing intermediate coding).
To broadcast a laptop to TV, it is recommended to purchase a VGA to SCART adapter. The first is often found on computers and laptops, the second on television sets.
Outdated analog interface with low quality video (576i, 480i). It cannot reproduce the new formats used today. Yes, and TVs with this port are almost never found (except for old models).
How to View your Laptop on your TV
However, if you want to connect your laptop to a TV, there is a way. through an S-Video-RCA adapter (“tulips”). It is not worth taking a cable longer than 2 meters. this will significantly reduce the signal quality.
If you use a USB-USB connection, video viewing will not be available, since the standard does not provide for the transfer of video data. But there will be access to pictures, presentations, text documents. That is, TV will perceive the laptop as a USB flash drive.
To transfer video data, you will need a USB cable and an adapter for it, which is an external video card. When buying it, they look at the parameters of the audio signal and support for the FullHD format. The adapter is connected to the TV, and the drivers are installed on the laptop. Then on TV change the signal source to “USB”.
Unlike Wi-Fi, LAN is a wired network connection (via the Ethernet port). The method is relevant if the TV does not have a Wi-Fi module.
To project a laptop screen onto a TV, the steps are the same as for a Wi-Fi connection:
Scheme of LAN connection of a laptop to a TV.
- The router and the TV receiver are connected with a network cable. The DCHP dynamic configuration protocol is configured on the network equipment. If this is not done, the parameters are entered manually already on the TV.
- The laptop is connected to the same network (via wire or wireless technology).
- They put the program “Home Media Server” on the laptop, one of the functions of which is to display content on TV.
- Share folders.
Everything, there is a connection, it remains to choose the content that will be broadcast on the large display.
A popular connector found on newer TVs, PCs and DVD players. Signal transmission. analog, but no sound. The video quality is quite good. 1600 x 1200 pixels. Often on the equipment, this port is signed as a PC, which implies a connection to a laptop screen or a computer monitor.
To reproduce the sound, they buy an adapter for “tulips”. Another option is to make sure that the sound is output through the laptop speakers (you can connect speakers to it).
To form a color picture, the system reads 3 signals: R. red, G. green, B. blue. If this connector is used to output the image, then it must also be on the TV.
The RGB interface appeared after SCART (replaced, since the latter was not suitable for TVs with a thin case). It is usually found on older TV models.

Which way to choose
There are several options for duplicating an image from a laptop to a PC. Here you need to build on the ports that are available in technology. It is not always possible to do this directly, but adapters come to the rescue in such situations.
USB to HDMI adapter.
If we compare a wired connection with a wireless one, the first one wins, due to better bandwidth and signal stability. But, if you do not have the necessary cords at hand, and you do not want to pile up the wires, they synchronize “over the air” using wireless wi-fi technology.
As for the wired connection, the newer the interface, the better. HDMI is considered optimal. It is he who is used to transmit video and audio in high quality.
During setup, the user may encounter the following problems:
- nothing happens when the cable is connected. The cord or one of the ports may be damaged. In such a situation, the picture is either not displayed at all or “breaks down”;
- the wireless connection is not working. The signal can simply be weak (especially if there are many obstacles in the room). And for the transmission of high-quality content, a stable high-speed Internet is required;
- there is no “Source” button on the remote. Some manufacturers leave it unsigned. As a rule, it is located near the power button and looks like an arrow entering a square;
- old technique, even without VGA. An adapter will help in such a situation: on one side there are tulips, on the other. VGA / DVI.
There are enough ways to display a picture from a laptop on a TV screen. Everyone is free to choose which one he likes best. For watching movies in high quality, playing games, a wired connection is recommended. If you plan to open photographs, documents or simple files on the TV set, the option “by air” is also suitable.
